1. Turn the ignition switch to the ON position.
2. Program the sun roof actuator. Refer to Programming the Sun Roof Actuator for programming procedures.
3. Turn the sun roof switch knob to position A. The sun roof should move to the fully open position.
4. Turn the sun roof switch knob to position C. The sun roof should close approximately 50%.
5. Turn the sun roof switch knob to position E. The sun roof should move to the fully closed position.
6. Turn the sun roof switch knob to position G. The sun roof should move to the fully tilted position.

Does the sun roof move to the different positions when the sun roof switch knob is moved to the different positions?

1. Turn the sun roof switch knob to position A and wait until the sun roof is completely open.
2. Turn the sun roof switch knob to position E so that the sun roof will move to the fully closed position.
3. As the sun roof is closing, use something to obstruct the sun roof from fully closing.
4. When the sun roof actuator detects that there is an obstruction, it is supposed to stop and open to a predetermined position.
